An in-depth analysis of thread-local storage (TLS) performance in C++, examining how different implementations and contexts affect access speed. Core findings show that TLS access is fastest in executables without constructors, while shared libraries and constructors significantly degrade performance due to complex initialization and addressing mechanisms.
